The glass innovation that made a revolutionary impact on a century of scientific exploration

Corning Incorporated (NYSE: GLW) this year is celebrating the 100th anniversary of the PYREX® brand, representative of an innovation that has become one of the world’s most trusted names. For a century, Corning’s PYREX glass has been at the heart of groundbreaking discoveries and advancements in medicine, chemistry, space exploration, and other fields.

“PYREX glass is a great example of Corning’s expertise in materials science and our legacy of translating science into life-changing products that benefit the world. PYREX glass demonstrates Corning’s sustaining technology and product life cycles,” said Dr. David L. Morse, executive vice president and chief technology officer.

The PYREX brand has been trusted by scientists for 100 years and remains the leading brand of glassware found in labs around the world today.

“From large research facilities to medical centers to local high school labs, PYREX labware is there,” said Dr. Richard Eglen, vice president and general manager, Corning Life Sciences.

The same qualities that made PYREX glass ideal for its initial application of cookware — transparency, strength, and chemical resistance – were also qualities that met the demands of laboratory chemists and scientists from its inception. The outbreak of World War I had prevented American scientists from accessing specialty European glass common in laboratories at the time.

The introduction of PYREX glass in 1915 gave American scientists a replacement that was not only suitable, but superior to the products they had been importing from Europe in terms of chemical stability and heat resistance. Indeed, in 1918, the U.S. Bureau of Standards gave PYREX glass a higher rating than any other known glass for labware.

Today, Corning’s PYREX laboratory glassware has become the accepted standard in chemistry labs across the globe, ideal for most laboratory glass applications. With more than 2,400 products now available, Corning’s PYREX labware remains a keystone product in important global industries such as chemical research and vaccine production.

Over the last 100 years, PYREX glass has played a key role in a variety of innovative, historic and life-changing achievements and applications:

In 1913, Bessie Littleton, wife of Corning physicist Dr. Jesse Littleton, baked a cake on a piece of heat-resistant glass being developed at the time — which laid the foundation for the PYREX brand. Corning excelled in the consumer products market for more than 80 years, before selling the business in 1998.

The first radio message from the South Pole was transmitted over radio antennas using PYREX insulators — which helped preserve maximum strength and clarity of radio impulses, critical to safety in the development of air travel and exploration.

In 1935, the Hale Telescope on Palomar Mountain in California was made from a 200-inch, 20-ton disk of PYREX glass and was, at the time, the largest glass disk ever manufactured. In 1937, PYREX glass was made into tiny bottles to store doses of insulin since the glass was less likely to react with its contents.

PYREX glass products played an important role in enabling the mass commercialization of penicillin during World War II.

In the 1950’s, Dr. Jonas Salk grew the original cultures for his polio vaccine in PYREX Fernbach flasks.

For more than 160 years, Corning has applied its unparalleled expertise in specialty glass, ceramics, and optical physics to develop products, including PYREX glass that has transformed people’s lives. By fine-tuning the formulation and fabrication of glass, Corning scientists will continue to unleash a nearly limitless stream of new capabilities for the future.
